Diamond in the rough?

It was well known that the Vikings needed to add depth to the OL. Picking Kalil 4th overall solidified the left side of the line, allowing Johnson to move to LG where even he feels he is more comfortable. But I was a bit surprised, but not disappointed when the Vikings started trading some of their picks for picks in 2013. And while I feel we would have been better taking an offensive lineman with the 128th pick, there's nothing I can do about that. So it's no surprise that the Vikings are bringing in 3 offensive lineman as undrafted free agents. Then while I was plugging around on NFL.com, I came across this:

Mayock's Position Rankings

NFL Network draft analyst Mike Mayock ranks his top five players by position for the 2012 draft. Check back regularly to see Mayock's latest updates to the lists.

Centers:
1. Peter Konz, Wisconsin, Drafted Round 2, Pick 23 (55th overall) by Falcons
2. Philip Blake, Baylor, Drafted Round 4, Pick 13 (108th overall) by Broncos
3. Ben Jones, Georgia, Drafted Round 4, pick 4 (99th overall) by Texans
4. David Molk, Michigan, Drafted Round 7, pick 19 (226th overall) by Chargers.
5. Quientin Saulsberry, Mississippi State

		Quientin Saulsberry is highlighted because he was undrafted. And because of that, the Vikings agreed to terms with him as an undrafted free agent. This could be a big news for an O-line that could use compentent back ups. We already got Mayock's number 1 OT with Kalil and number 2 S with Smith, now we have his number 5 C.
